Short-term lethality and sediment avoidance assays with endrin-contaminated sediment and two oligochaetes from Lake Michigan.
Mean 96-hr LCs0 values and standard deviations for the oligochaetes S. heringianus and L. hoffmeisteri exposed to endrin-contaminated sediment were 2,588 _ 1,974 txg/g dry weight sediment for 4 assays and 2,725 + 955 Cg/g for 2 assays, respectively. Mixed species testing data suggested that the toxicity to L. hoffrneisteri was reduced in the presence of S. heringianus, yet further testing is re...

15 صفحه اولInfection of Oligochaetes, Limnodrilus hoffmeisteri (Annelida: Oligochaeta), in the Nasal Cavity of a Chinese Man
The infection by Limnodrilus hoffmeisteri Claparède, 1862 (Oligochaeta: Tubificinae) in humans is relatively uncommon. The present report is to describe an incidental human infection with oligochaetes in the nasal cavity of a Chinese man, a 25-year-old man residing in Zhangjiakou city, Hebei province, China presenting with nose bleed, severe itching, continuous sneezing, and rhinorrhea. A lot o...
متن کاملLoss of evolutionary resistance by the oligochaete Limnodrilus hoffmeisteri to a toxic substance--cost or gene flow?
The oligochaete Limnodrilus hoffmeisteri at Foundry Cove (FC), New York evolved genetic resistance to cadmium (Cd) and lost resistance after contaminated sediments were removed by dredging. Selection (on survival time in dissolved Cd) was used to generate tolerance to evaluate fitness cost, the commonplace expectation for evolutionary reversal. The hypothesis that gene flow from neighboring pop...
متن کاملExposure of few layer graphene to Limnodrilus hoffmeisteri modifies the graphene and changes its bioaccumulation by other organisms.
While graphene has substantial commercial promise, numerous aspects regarding its ecological effects such as its potential for bioaccumulation are not well known. 14C-labeled few layer graphene (FLG) was dispersed in artificial freshwater and uptake of FLG by Limnodrilus hoffmeisteri, an oligochaete, was assessed. After exposure for 36 h to a 1 mg/L FLG suspension, the FLG body burden in the or...
